During last 20-30 years many researchers have paid attention to studies of properties of the wood plastics composites (WPC). A lot of works are close related to investigations of exploitation properties of wood fibres or flour containing polyolefine composites [1]. The most useful from wide selection of polyolefines are polypropylenes, but as reinforcement of WPC often are used different waste materials comprising lignocellulose fibres. Such materials also are a lot of waste which produce timber industry. In this work we approbated for reinforcing of polypropylene (PP) one of the waste product of plywood technology-plywood sawdust (PSWD), which contain wood fibres fractions with different length (l). The main fraction (50% ) have fibres with length l=0.5-1 mm. Our previous studies [2] showed that PSWD is promising filler for PP reinforcing. That additions of the PSWD up to 40-50 wt.% increase WPC tensile and flexural modulus, but decrease deformation ability of PP matrix, impact strength, water resistance and fluidity of composite melts. Modification of the composites with interfacial modifier maleated polypropylene (MAPP up to 5-7 wt.%) considerably improve all the above-mentioned properties. One more way how to make better properties of the WPC is to form hybridcomposites. Very popular WPC modifiers are nanoparticles additions like nanoclays which increases WPC physical-mechanical properties, microhardness, water resistance and diminish combustibility. The goal of this study is to investigate nanoclays influence on PSWD containing WPC composites physical-mechanical properties. As polymer matrix PP type Mosten MA-712 was used, but as modifiers Licocene PP MA-7452 and nanoclays grade Cloisite 15A. Composites were prepared by mixing on two rolls mill, then cooled, granulated and pressed in 1 mm thick sheets for tensile strength measurements (ASTM D 638M). Tensile, flexural and impact strength tests were done.for standard specimens (EN ISO 178 and ASTM D 256M respectively) bars produced by injection moulding. Melt fluidity (melt flow index-MFI) was estimated by standard ASTM D 1238. Water resistance measurements were done according to the standard ASTM D 570-88. From previous [2] studies as optimal composition of the composite containing PSWD was chosen PP+40 wt.%WF+7.0 wt.% MAPP. Changing nanoclays amout and controling tensile, flexural and impact strength properties was noted optimal concentration of nanoclays in the composite (3wt.%). Then was examined MAPP influence on mentioned properties and optimal concentration was gained 7wt.%. As result of these studies was found optima l composition of hybrid composite based on polypropylene and 40 wt.% of PSWD+3wt.% nanoclay+7wt.% MAPP which have better mechanical properties than composites without nanoclays. Additons of nanoclays improve also fluidity of investigated hybrid composites (MFI reaches 6g/10min) and increase of water resistance.
